- Confinement during the COVID-19 pandemic is expected to have a serious and complex impact on the mental health of patients with an eating disorder (ED) and of patients with obesity. The present manuscript has the following aims: (1) to analyse the psychometric properties of the COVID Isolation Eating Scale (CIES), (2) to explore changes that occurred due to confinement in eating symptomatology; and (3) to explore the general acceptation of the use of telemedicine during confinement. The sample comprised 121 participants (87 ED patients and 34 patients with obesity) recruited from six different centres. Confirmatory Factor Analyses (CFA) tested the rational-theoretical structure of the CIES. Adequate goodness-of-fit was obtained for the confirmatory factor analysis, and Cronbach alpha values ranged from good to excellent. Regarding the effects of confinement, positive and negative impacts of the confinement depends of the eating disorder subtype. Patients with anorexia nervosa (AN) and with obesity endorsed a positive response to treatment during confinement, no significant changes were found in bulimia nervosa (BN) patients, whereas Other Specified Feeding or Eating Disorder (OSFED) patients endorsed an increase in eating symptomatology and in psychopathology. Furthermore, AN patients expressed the greatest dissatisfaction and accommodation difficulty with remote therapy when compared with the previously provided face-to-face therapy. The present study provides empirical evidence on the psychometric robustness of the CIES tool and shows that a negative confinement impact was associated with ED subtype, whereas OSFED patients showed the highest impairment in eating symptomatology and in psychopathology.

Journal article (peer-reviewed)abstract
- The proper functional interaction between different tissues represents a key component in systemic metabolic control. Indeed, disruption of endocrine inter-tissue communication is a hallmark of severe metabolic dysfunction in obesity and diabetes. Here, we show that the FNDC4-GPR116, liver-white adipose tissue endocrine axis controls glucose homeostasis. We found that the liver primarily controlled the circulating levels of soluble FNDC4 (sFNDC4) and lowering of the hepatokine FNDC4 led to prediabetes in mice. Further, we identified the orphan adhesion GPCR GPR116 as a receptor of sFNDC4 in the white adipose tissue. Upon direct and high affinity binding of sFNDC4 to GPR116, sFNDC4 promoted insulin signaling and insulin-mediated glucose uptake in white adipocytes. Indeed, supplementation with FcsFNDC4 in prediabetic mice improved glucose tolerance and inflammatory markers in a white-adipocyte selective and GPR116-dependent manner. Of note, the sFNDC4-GPR116, liver-adipose tissue axis was dampened in (pre) diabetic human patients. Thus our findings will now allow for harnessing this endocrine circuit for alternative therapeutic strategies in obesity-related pre-diabetes.

- Background: Alcohol use is a leading risk factor for death and disability, but its overall association with health remains complex given the possible protective effects of moderate alcohol consumption on some conditions. With our comprehensive approach to health accounting within the Global Burden of Diseases, Injuries, and Risk Factors Study 2016, we generated improved estimates of alcohol use and alcohol-attributable deaths and disability-adjusted life-years (DALYs) for 195 locations from 1990 to 2016, for both sexes and for 5-year age groups between the ages of 15 years and 95 years and older.Methods: Using 694 data sources of individual and population-level alcohol consumption, along with 592 prospective and retrospective studies on the risk of alcohol use, we produced estimates of the prevalence of current drinking, abstention, the distribution of alcohol consumption among current drinkers in standard drinks daily (defined as 10 g of pure ethyl alcohol), and alcohol-attributable deaths and DALYs. We made several methodological improvements compared with previous estimates: first, we adjusted alcohol sales estimates to take into account tourist and unrecorded consumption; second, we did a new meta-analysis of relative risks for 23 health outcomes associated with alcohol use; and third, we developed a new method to quantify the level of alcohol consumption that minimises the overall risk to individual health.Findings: Globally, alcohol use was the seventh leading risk factor for both deaths and DALYs in 2016, accounting for 2.2% (95% uncertainty interval [UI] 1.5-3.0) of age-standardised female deaths and 6.8% (5.8-8.0) of age-standardised male deaths. Among the population aged 15-49 years, alcohol use was the leading risk factor globally in 2016, with 3.8% (95% UI 3.2-4-3) of female deaths and 12.2% (10.8-13-6) of male deaths attributable to alcohol use. For the population aged 15-49 years, female attributable DALYs were 2.3% (95% UI 2.0-2.6) and male attributable DALYs were 8.9% (7.8-9.9). The three leading causes of attributable deaths in this age group were tuberculosis (1.4% [95% UI 1. 0-1. 7] of total deaths), road injuries (1.2% [0.7-1.9]), and self-harm (1.1% [0.6-1.5]). For populations aged 50 years and older, cancers accounted for a large proportion of total alcohol-attributable deaths in 2016, constituting 27.1% (95% UI 21.2-33.3) of total alcohol-attributable female deaths and 18.9% (15.3-22.6) of male deaths. The level of alcohol consumption that minimised harm across health outcomes was zero (95% UI 0.0-0.8) standard drinks per week.Interpretation: Alcohol use is a leading risk factor for global disease burden and causes substantial health loss. We found that the risk of all-cause mortality, and of cancers specifically, rises with increasing levels of consumption, and the level of consumption that minimises health loss is zero. These results suggest that alcohol control policies might need to be revised worldwide, refocusing on efforts to lower overall population-level consumption.

Conference paper (peer-reviewed)abstract
- Digitalization is changing the business environment and companies face challenges to make progress. A first step to support companies is to verify their digital readiness, capabilities, and developing clear plans for improvement. This paper aims to evaluate the digital readiness of seven companies through the application of a self-check tool, followed by a deeper investigation through a case study, to identify reasons, challenges/barriers and enablers towards digitalization. A workshop was conducted to evaluate the use of a self-check tool and collect other analysis. Results include the readiness level and comparison between companies, actions and practices towards increased digitalization.

Interleukin-1 beta-induced memory reconsolidation impairment is mediated by a reduction in glutamate release and zif268 expression and alpha-melanocyte-stimulating hormone prevented these effects
- 2015

Journal article (peer-reviewed)abstract
- The immune system is an important modulator of learning, memory and neural plasticity. Interleukin 1 13 (IL-1 beta), a pro-inflammatory cytokine, significantly affects several cognitive processes. Previous studies by our group have demonstrated that intrahippocampal administration of IL-1 beta impairs reconsolidation of contextual fear memory. This effect was reversed by the melanocortin alpha-melanocyte-stimulating hormone (alpha-MSH). The mechanisms underlying the effect of IL-1 beta on memory reconsolidation have not yet been established. Therefore, we examined the effect of IL-1 beta on glutamate release, ERK phosphorylation and the activation of the transcription factor zinc finger- 268 (zif268) during reconsolidation. Our results demonstrated that IL-1 beta induced a significant decrease of glutamate release after reactivation of the fear memory and this effect was related to calcium concentration in hippocampal synaptosomes. IL-1 beta also reduced ERK phosphorylation and zif268 expression in the hippocampus. Central administration of a-MSH prevented the decrease in glutamate release, ERK phosphorylation and zif268 expression induced by IL-1 beta. Our results establish possible mechanisms involved in the detrimental effect of IL-1 beta on memory reconsolidation and also indicate that a-MSH may exert a beneficial modulatory role in preventing IL-1 beta effects.

Performance of timing Resistive Plate Chambers with protons from 200 to 800 MeV
- 2015
-
In: Journal of Instrumentation. - 1748-0221. ; 10:1, s. C01043-
-
Journal article (peer-reviewed)abstract
- A prototype composed of four resistive plate chamber layers has been exposed to quasi-monoenergetic protons produced from a deuteron beam of varying energy (200 to 800 AMeV) in experiment S406 at GSI, Darmstadt, Germany. The aim of the experiment is to characterize the response of the prototype to protons in this energy range, which deposit from 1.75 to 6 times more energy than minimum ionizing particles. Each layer, with an active area of about 2000 × 500 mm 2 , is made of modules containing the active gaps, all in multigap construction. Each gap is defined by 0.3 mm nylon mono-filaments positioned between 2.85 mm thick float glass electrodes. The modules are operated in avalanche mode with a non-flammable gas mixture composed of 90% C 2 H 2 F 4 and 10% SF 6 . The signals are readout by a pick-up electrode formed by 15 copper strips (per layer), spaced at a pitch of 30 mm, connected at both sides to timing front end electronics. Results show an uniform efficiency close to 100% along with a timing resolution of around 60 ps on the entire 2000 × 500 mm 2 area.

What motivates heart transplantation patients to exercise and engage in physical activity? A network analysis
- 2023
-
In: European Journal of Cardiovascular Nursing. - : OXFORD UNIV PRESS. - 1474-5151 .- 1873-1953.
-
Journal article (peer-reviewed)abstract
- Aims After heart transplantation (HTx), increments in physical activity (PA) are strongly recommended. However, participation rates in exercise-based cardiac rehabilitation and engagement in PA are insufficient in many patients. Hence, this study aimed to explore the central factors and the interconnections among distinct types of motivation to exercise, PA, sedentary time, psychosomatic, diet, and activity limitation characteristics in post-HTx patients. Methods and results This is a cross-sectional study involving 133 post-HTx patients (79 men, mean age 57 +/- 13 years, mean time from transplantation 55 +/- 42 months) recruited from an outpatient clinic in Spain. The patients were asked to fill in questionnaires measuring self-reported PA, motivation to exercise, kinesiophobia, musculoskeletal pain, quality of sleep, depression, functional capacity, frailty, sarcopenia risk, and diet quality. Two network structures were estimated: one network including PA and one network including sedentary time as nodes. The relative importance of each node in the network structures was determined using centrality analyses. According to the strength centrality index, functional capacity and identified regulation (subtypes of motivation to exercise) are the two most central nodes of the network (strength: z-score = 1.35-1.51). Strong and direct connections emerged between frailty and PA and between sarcopenia risk and sedentary time. Conclusion Functional capacity and autonomous motivation to exercise are the most promising targets of interventions to improve PA levels and sedentary time in post-HTx patients. Furthermore, frailty and sarcopenia risk were found to mediate the effects of several other factors on PA and sedentary time.
